Provided is a particulate water-absorbent agent having suppressed reduction of absorption capacity, after elapse of a long time, good gel layer diffusion performance and reduced Re-wet, a water-absorbent goods containing the water-absorbent agent, and a production method for the water-absorbent agent. The above problem is solved by a particulate water-absorbent agent having a polyacrylate salt-type water-absorbent resin as a main component, and having an absorption capacity without load of equal to or higher than 28 g/g, characterized by satisfying the following (a) to (c): (a) amount of water-soluble component under stirring is from 15 to 60% by mass (b) difference between an amount of water-soluble component under stirring and an amount of water-soluble component in standing still (amount of water-soluble component under stirring - amount of water-soluble component in standing still) is from 15 to 50% by mass and (c) diffusion absorption index is from 1.40 to 10.0 g/g/min wherein the amount of water-soluble component under stirring represents amount of a dissolution polymer after 16 hours, to a normal saline solution under stirring, and the amount of water-soluble component in standing still represents amount of a dissolution polymer after 16 hours, to a normal saline solution in standing still.
